"Nail-bitingly suspenseful and refreshingly witty." --Kirkus
"Readers will enjoy the quirky questing tasks, including a high-stakes playground game, and the tricky vicissitudes of bright magic that opposes harmful shadow magic but has abundant quirks of its own. Grounding the fun is a more serious thread in which Oscar and Imogen realize the extent to which they have each been failed by adults in their lives and learn that it is okay to be taken care of instead of constantly caring for others' needs. The group makes a loving found family through their obvious affection and admiration for one another and much cousinly squabbling." -- Bulletin of the Center for Children's Books
